6.2.2 Swivel Hitch
If a TOOMEY swivel hitch has been supplied follow the instructions below. If an alternate brand
hitch has been supplied, consult the maintenance documentation from that manufacturer.
Pump grease into each of the three grease ports located on the left side of the hitch. Pump
grease until grease starts to appear between the thrust washers either top of bottom.
After the initial bedding-in period the nut on the horizontal shaft may need tightening to remove
any play that has developed.
The shorter the intervals between application of grease the longer the bushes and thrust
washers will last. For maximum life it is recommended that the swivel hitch be greased using an
automated system using smaller dosage more frequently.
Figure 6.2 Hitch Grease Points
NOTE: For the first 24 hours of operation, add a pump or two of grease every 3 hours to
ensure grease is worked into all the thrust discs. You will get best results if you alternate load
on the hitch each time grease is added i.e. reverse tractor, lift hitch cylinder, lower hitch
cylinder etc.
NOTE: Ensure the 3” locking nut on the horizontal shaft remains tight to inhibit movement
between it and the shaft. Movement between the nut and the shaft will result in damage to
the thread and will not be covered under warranty.
